To all whom it may concern: ment of the lever D in one direction in the Be it known that we, FRANCIS G. BATES and carrier.

FRANK II. BATES, citizens of the United States, The pawlF has two gripping points or teeth and residents of Philadelphia, Pennsylvania, so, formed by recessing that face of the pawl have invented certain Improvements in which is adjacent to the stem A of the tool, 5 5

Ratchet-Tools, of which the following is a and either of these gripping-points may be specification. made the active one, depending upon whether The object of our invention is to construct the tool is to be right-handed or left-handed,

a ratchet-tool which will be noiseless in operand this in turn is dependent upon the locaro ation, but which will provide for a powerful tion of the stop-pin 19. For instance, when grip upon the stem of the tool and which can this pin is adjusted as in Figs. 2 and 3 the be readily changed from a right-handed tool tool is right-handed, a forward pull upon the to a left-handed tool. This object we attain lever D in the direction of the arrow, Fig. 2, in the mannerhereinaftersetforth, reference serving to first bring the gripping-point 0:

It will be evident, therefore,

This hold upon the stem A is insured by reason of carrier 13 is in the presentinstance composed the fact that the pawl grips said stem through- 3 5 of two portions f and g, one above the other, out the entire length between the collarb and each portion of the carrier-having an opening nut (Z.
